The birth of this fan embodies ebm-papst's years of experience and wisdom in the field of ventilation technology, providing users with efficient and stable ventilation solutions.
（1） Part number
The unique part number R3G250-RR01-H1 is the exclusive identifier for this fan. It not only contains the basic information of the product, such as fan type, size, etc., but also facilitates users to accurately identify and match in the selection, procurement, and after-sales service stages. Through this number, users can quickly search for detailed technical information and related accessory information of the fan.
（2） Fan type
R3G250-RR01-H1 belongs to centrifugal fans. The working principle of a centrifugal fan is to use the high-speed rotation of the impeller to move air from the center to the edge of the impeller under the action of centrifugal force, thereby achieving air transportation and pressurization. This working method gives centrifugal fans significant advantages in providing high pressure and large air volume, making them suitable for occasions with high ventilation requirements.
（3） Rated voltage
The rated voltage of the fan is 230V, which is a common standard voltage for industrial and commercial electricity. A stable 230V voltage input can ensure the stable operation of the fan motor, providing continuous and reliable power support for the fan. At the same time, this standard voltage design also enables wind turbines to be easily connected to various power systems, reducing users' difficulties in power adaptation.
（4） Size
The size of the fan is 250 millimeters, which is a moderate specification among centrifugal fans. The size of 250mm ensures that the fan has sufficient air handling capacity without being too large, making it easy to install and layout in various spatial environments. Whether inside small equipment or in large ventilation systems, R3G250-RR01-H1 can find a suitable installation location.
（5） Maximum air volume
The maximum air volume can reach 2210m ³/h, which is a considerable value. Such high air volume enables the fan to quickly deliver a large amount of air in a short period of time, meeting the ventilation and air exchange requirements of large spaces or places with high ventilation needs. For example, in large industrial plants, R3G250-RR01-H1 can quickly dissipate the heat, harmful gases, and dust generated during the production process, maintaining fresh and healthy indoor air.
（6） Maximum pressure
The maximum pressure is 1100Pa, which means that the fan has a strong ability to overcome resistance. In ventilation systems, factors such as pipe length, number of bends, and air filters can increase the resistance to air flow. The high pressure characteristics of R3G250-RR01-H1 enable it to easily handle these resistances, ensuring smooth air flow in ventilation ducts and achieving efficient ventilation effects.
（7） Input power
The input power is 500W, and the power consumption of the fan is at a reasonable level while ensuring high air volume and high pressure output. This is thanks to the advanced design concept and manufacturing process of ebm-papst, which improves the energy conversion efficiency of the fan, reduces energy consumption, and saves operating costs for users by optimizing the impeller structure and adopting efficient motors.
（8） Rotational speed
The speed is 4100rpm, and a higher speed is one of the key factors for the fan to achieve high air volume and high pressure. The rapidly rotating impeller can generate strong centrifugal force, quickly throwing air out, thereby achieving efficient air transportation. Meanwhile, a reasonable speed design also helps to control the noise level of the fan, ensuring that the fan operates efficiently without generating excessive noise interference.
（9） Noise
The noise level is 52dB, and the relatively low noise makes the fan quieter during operation. In noise sensitive environments such as hospitals, schools, offices, etc., the low noise characteristics of R3G250-RR01-H1 can provide users with a quiet and comfortable environment without causing interference to surrounding personnel and equipment.
（1） Efficient ventilation
The R3G250-RR01-H1 centrifugal fan exhibits excellent ventilation performance with a maximum air volume of 2210m ³/h and a maximum pressure of 1100Pa. Whether it is ventilation in industrial production or air conditioning in commercial buildings, this fan can quickly and effectively meet ventilation needs, ensuring ideal indoor air quality.
（2） Energy saving and efficient
Despite having strong ventilation capabilities, the input power of this fan is only 500W, demonstrating excellent energy-saving performance. By optimizing the aerodynamic design of the impeller, ebm-papst reduces the resistance of air flow and improves the efficiency of the fan. At the same time, the use of efficient motors and advanced control technology further reduces the energy consumption of the fan, achieving the goal of high efficiency and energy conservation.
（3） Low noise operation
The noise level of 52dB makes R3G250-RR01-H1 very quiet during operation. This is due to its carefully designed impeller shape and structure, as well as high-quality materials and precise manufacturing processes. These factors work together to effectively reduce turbulence and vibration in the air flow process, thereby reducing the generation of noise.
（4） Sturdy structure
The fan adopts high-quality materials and a sturdy structural design, ensuring its stability and reliability during long-term operation. The shell can effectively resist external impact and corrosion, and the key components such as impellers and motors inside have undergone strict testing and screening, with good high temperature resistance, moisture resistance, and wear resistance.
（5） Easy installation
The design of R3G250-RR01-H1 fully considers the convenience of installation. It has a compact structure, standard installation dimensions, and is equipped with detailed installation instructions and necessary installation accessories. Users can easily install the fan into the ventilation system according to the instructions in the manual, greatly saving installation time and costs.
